The Small Fix That Makes a Big Difference
Changing your HVAC filter is one of the easiest and most cost-effective ways to improve your indoor air quality, extend the life of your system, and even lower your energy bills. Yet it’s one of the most commonly overlooked home maintenance tasks. A dirty or clogged filter forces your system to work harder, uses more energy, and can spread dust and allergens throughout your home. Staying on top of filter changes keeps your air clean and your comfort consistent — especially in Utah’s dry, dusty climate.
When to Change Your Filter (and When Sooner is Better)
While most standard filters should be replaced every 30 to 60 days, some households need more frequent attention:
- Pets or allergies? Every 20–30 days is best to keep dander and particles at bay.
- Vacation home or light use? You might stretch it to 90 days — but inspect monthly to be safe.
- Live near fields or construction? Shorter intervals can prevent clogging from outside dust.
If you notice reduced airflow, increased allergy symptoms, dusty vents, or higher energy bills, your filter may already be overdue. Set a calendar reminder or subscribe to a filter delivery service so it never slips your mind again.
Signs You’re Overdue for a Filter Change
Still unsure if it’s time? Watch for these common signs:
- Return vents covered in dust
- HVAC unit running longer or more frequently
- Strange odors when your system kicks on
- Higher-than-normal electric bills
- Visible dirt buildup on the filter itself
A clean filter not only protects your system — it protects your family’s health, too.
